Answer 1

Explanation:

Point A maps into point G, point B maps into point H and point C maps into point J. To name the triangle we have to follow the same order of letters. If the first triangle is ABC, the second is GHJ.

The second triangle is smaller. A dilation can be a stretch or a shrink, depending on the scale factor. If it's greater than 1, it's a stretch. If it's less than 1, it's a shrink.

Both triangles have the same angles and a constant ratio between corresponding sides, so they are similar.

Answers:

Each coordinate of ΔABC can be multiplied by 1/3 to give the corresponding coordinate of ΔGHJ. The transformation of ΔABC to ΔGHJ is a dilation with a scale factor of 1/3. Therefore, the triangles are similar.
